Experimental data: Low-velocity out-of-plane impact tests on double-wythe unreinforced brick masonry walls instrumented with optical measurements

This dataset includes the results of laboratory impact tests conducted on natural-scale double-wythe unreinforced brick masonry walls. The walls were spanning vertically between two reinforced concrete slabs and were subjected to low-velocity drop-weight pendulum tests in which they were repeatedly hit until the opening of a breach in the center of the wall. The tests were instrumented with both hard-wired and optical measurements, the latter consisting of high-speed cameras and digital image correlation techniques. Investigated in these tests were the out-of-plane response of the walls and their capacity to resist the impacts. The axial load applied on the top of the walls was varied for two wall configurations and monitored throughout the tests to study the effect of arching on the failure mechanism produced and number of repeated hits needed to open the breach. Of interest was also the evidence of cracking, more specifically the way it initiated on the undamaged walls and next propagated upon consecutive hits. The data generated from the tests is made here available and documented to support further investigations on masonry structures subjected to extreme actions. The dataset includes four ZIP files, ordered from 01 to 05, along with an auxiliary PDF document describing the content and organization of the data. Test implementation and test results that are built upon this data are presented and discussed in the following research article: Godio M, Flansbjer M, Williams Portal N (2023) Low-velocity out-of-plane impact tests on double-wythe unreinforced brick masonry walls instrumented with optical measurements, International Journal of Impact Engineering (https://www.sciencedirect.com/science/article/pii/S0734743X23001082?via%3Dihub) To cite this data in your work please refer to the article. The Authors本数据集收录了针对足尺双层无筋砖砌体墙（double-wythe unreinforced brick masonry walls）开展的实验室冲击试验结果。试验墙体支承于两块钢筋混凝土楼板（reinforced concrete slabs）之间，并接受低速落锤摆锤冲击试验（low-velocity drop-weight pendulum tests）：墙体将被反复冲击，直至其中部形成破口。本次试验同时采用有线测量与光学测量方案，其中光学测量包含高速相机与数字图像相关技术（digital image correlation techniques）。本试验旨在研究墙体的面外响应（out-of-plane response）及其抗冲击性能。针对两种墙体构造形式，研究人员对墙体顶部施加的轴向荷载（axial load）进行了调整，并在整个试验过程中对其进行监测，以分析拱效应（arching）对试验产生的破坏机制以及形成破口所需的重复冲击次数的影响。此外，本次试验还关注墙体的开裂特征：具体包括未损伤墙体的开裂起始模式，以及后续连续冲击下的开裂扩展路径。 本数据集公开并完整记录了本次试验所得数据，旨在为承受极端荷载作用（extreme actions）的砌体结构相关后续研究提供支撑。数据集包含编号01至05的四个ZIP压缩文件（ZIP files），以及一份用于说明数据集内容与组织结构的辅助PDF文档（PDF document）。 基于本数据集开展的试验实施细节与试验结果，已在以下研究论文中进行阐述与讨论： Godio M, Flansbjer M, Williams Portal N (2023) 带光学测量的双层无筋砖砌体墙低速面外冲击试验，《国际冲击工程学报（International Journal of Impact Engineering）》(https://www.sciencedirect.com/science/article/pii/S0734743X23001082?via%3Dihub) 若需在您的研究中引用本数据集，请参考上述论文。 作者
